Er, the big mail services mostly just silently drop mail they don’t like, as
far as I can tell, and they don’t tend to do policies like we’re discussing
here: they just evaluate how likely the mail is to be something the reader
wants to see, and deliver it or junk it on that basis. You are right that
they do a very good job of it, but it’s quite an expensive job, and that’s part
of my criticism: it need not be nearly so expensive, and it need not be
something only big companies can do.
This conversation is specifically about a problem with IETF mailing lists, so
the points I was making do apply here. I am in fact curious to hear if the
big mail providers are doing things like what I described in the previous
message—if so, that’s cool in principle. But if it’s not described in the
RFCs, you haven’t actually contradicted the point I was making, which is that
it ought to be reflected in the standards.
